Inspect the radio face plate. The radio sales code is printed on the face of the radio (Figure 1). If the vehicle is equipped with an "RAZ" radio, it
must be removed from the instrument panel and completely disconnected to eliminate the possibility of any electronic communication between the
radio and the instrument cluster during the flash procedure.
13.
Vehicles equipped with a "RAZ" radio: remove the ABS module fuse (# 35) from the Power Distribution Center (PDC) (Refer to the bottom of the
PDC cover for fuse location). This will prevent any communication between the ABS module and the instrument cluster during the flash
procedure.
CAUTION:
The flash process will fail if you are attempting to flash a "RAZ" radio equipped vehicle without disconnecting the radio and removing the ABS
module fuse as outlined in Steps 12 and 13.
14.
Install a battery charger and verify that the charging rate provides approximately 13.5 volts. The charger needs to be charging the battery for the
entire flash session.
15.
Connect the DRBIII to the vehicle.
16.
Turn the ignition key to the "RUN" position.
17.
Download the flashes from the DRBIII to the vehicle.
NOTE:
On 2003 model vehicles, the DRBIII will select the correct flash for the FCM based on the FCM part number in the vehicle. Using the DRBIII:
a.
Select "Vehicle Flash".
b.
Follow the directions on the DRBIII screen. When the flash process is complete, proceed to Step 18.
18.
If removed, install fuse # 35 into the PCD.
19.
If the radio was removed, reconnect all radio connections, install the radio and radio bezel.
20.
Due to the programming procedure, a Diagnostic Trouble Code (DTC) may be set in other modules (PCM, TCM, BCM, SKIM, etc.) within the
vehicle, if so equipped. Some DTC's may cause the MIL to illuminate. Check all modules using "Module Scan" record the DTC's, and erase these
DTC's prior to returning the vehicle to the customer. Erase any DTC's in the PCM only after all other modules have had their DTC's erased.
21.
Disconnect the DRBIII scan tool from the vehicle.
